Kalanchoe plant named ‘Ingrid’

ABSTRACT

A new and distinct cultivar of  Kalanchoe  plant named ‘Ingrid’, characterized by its upright, uniform and moderately vigorous growth habit; dark green-colored leaves; uniform, freely and early flowering habit; relatively large light yellow-colored flowers; and excellent postproduction longevity.

Botanical designation: Kalanchoe blossfeldiana.

Cultivar denomination: ‘Ingrid’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Kalanchoe, botanically known as Kalanchoe blossfeldiana, and hereinafter referred to by the name ‘Ingrid’.

The new Kalanchoe is a product of a planned breeding program conducted by the Inventor in Hinnerup, Denmark. The objective of the breeding program is to create new freely-flowering Kalanchoe cultivars with attractive foliage and flower coloration.

The new Kalanchoe originated from a cross-pollination made by the Inventor in Hinnerup, Denmark in March, 2003, of the Kalanchoe blossfeldiana cultivar KJ 2000 0381, not patented, as the female, or seed, parent with the Kalanchoe blossfeldiana cultivar Ally, not patented, as the male, or pollen, parent. The cultivar Ingrid was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Hinnerup, Denmark in November, 2003.

Asexual reproduction of the new Kalanchoe by vegetative terminal cuttings in a controlled environment in Hinnerup, Denmark since February, 2004, has shown that the unique features of this new Kalanchoe are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Ingrid has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Ingrid’. These characteristics in combination distinguish ‘Ingrid’ as a new and distinct cultivar of Kalanchoe:

-   -   1. Upright, uniform and moderately vigorous growth habit.     -   2. Dark green-colored leaves.     -   3. Uniform, freely and early flowering habit.     -   4. Relatively large light yellow-colored flowers.     -   5. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the parent cultivars. Plants of the new Kalanchoe differ from plants of the parent cultivars primarily in plant size and flower color.

Plants of the new Kalanchoe can be compared to plants of the Kalanchoe blossfeldiana cultivar Ann, disclosed in U.S. Plant patent application Ser. No. 11/324,508. In side-by-side comparisons conducted in Hinnerup, Denmark, plants of the new Kalanchoe differed from plants of the cultivar Ann in the following characteristics:

-   -   1. Plants of the new Kalanchoe were more compact than plants of         the cultivar Ann.     -   2. Plants of the new Kalanchoe flowered earlier than plants of         the cultivar Ann.     -   3. Plants of the new Kalanchoe and the cultivar Ann differed in         flower color.

DETAILED BOTANICAL DESCRIPTION

The photographs and following observations, measurements and values describe plants grown in Hinnerup, Denmark in a glass-covered greenhouse during the winter and under conditions which closely approximate commercial production. During the production of the plants, day temperatures were about 19° C., night temperatures were about 21° C. and light levels ranged from 10 kilolux to 50 kilolux. Unrooted cuttings were directly stuck in 10-cm containers and received long day/short night conditions (more than 14 hours of light) for about two weeks; plants then received photoinductive short day/long night conditions (minimum 14 hours darkness) until flowering. Plants were about 15 weeks old when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
